Figure 5 is an'enlarged fragmentary sectional view of a modified feature of the invention. Y J Figure 6 is an end elevational view of Figure 5.

As shown on thedrawings: As illustrative ofthis invention there is shown a longitudinal base frame which is generally denoted by the reference numeral 1. 'llhis base frame comprises a support la for a motor 2. A lll-shaped guide frame 3 is attached to the base frame 1. This guide frame 3 slidably supports a bearing l upon 4@ which a motor 5 is mounted. rlLhe bearing 4 is sustained by means of a screw rod 6 which is rotatably anchored in the cross-piece 3a of :the U-shaped guide and which carries a beveled gear 7 at its upper end which meshes with a beveled pinion 8 secured upon the end g of a motor shaft 9, the motor 10 of which being supported upon an integral bracket l1 extending from the cross-piece 3a.` Obvious ly, the motor 10 may be operated for rotating thescrew rod 6 and raising or lowering the 50 bearing 4.

The lower end of the bearing 4 comprises a pair of spaced cylindrical bearings 12 in which a sleeve 13 is journalled, suitable bushings 14 being interposed between the sleeve 55 13 and the cylindrical bearings 12. The for- Ward end of the bearing sleeve 13 is provided with a radially extending flange 15. Within the bearing sleeve 13 there is a longitudinally adjustable roller 16 which may be adjusted nov to project a suitable distance beyond the radial flange 15. The roller 16 is slidably lreyed in the sleeve 13 as indicated at 16a. It

will be noted that the bushings 14 extend beyond the bearing 4 and just beyond the said 65 caring a spur gear 17 is keyed upon said sleeve and meshes with a pinion 18 which is secured upon the shaft of the aforementioned motor 5. An interiorly threaded collar 20 is anchored to the rear end of the sleeve 13 by 70 means of set screws. 21 or the like. A hand wheel 22is rotatably anchored upon the end of the roll 16 by means of combined radial and thrust bearing 23. This hand wheel is provided with an exteriorly threaded collar '24 which is in threaded engagement with the collar 20. A bolt 25 is mounted upon the collar 2O `and is adapted for engaging between a suitable serrated ridge 26 upon the hub of the hand wheel 22. It will be noted that the -bushings'14 are provided with flange ends which respectively t between the bearing 4 the gear 17 and the radial flange 15 of the sleeve 13 to protect the said bearing from undue wear. With reference to Figure 1, it will be noted/- that the. frame 1 comprises a platform-like support 1b at the top thereof upon which the guideframe 3 is supported. A movable bearing block 27 is supported upon the top portion 90 1b of said frame and is guided for longitudinal movementbetween suitable nguide blocks 28 (Figure 2) which overlap the lower lateral margins of the block 27 as clearly shown in Figure 2. A suitable lug 29 rises from the platform 1b and a screw rod 30 is threaded through the lug 29 at one end. The other end of the screw rod 30 is threaded in the bearing block 27. A jack collar 31 is secured upon the screw shaft 30 for engagement with an operating lever or the like, whereby the screw may be rotated for longitudinally adjusting the bearing block 27. The forward end of the base frame 1 is provided with a bearing 32 which is in axial alignment with a bearing aperture in the aforementioned bearing block 27 A sleeve 34 is journalled in the bearing 32 and bearing block 27 and is provided with a radial ange `adjacent the forward end of the bearing block 27. lt will be noted that the radial flange 35 is spaced a short distance from the radial flange 15 for a purpose that will later appear. A roll 36 is splined within the sleeve 34 and projects a short distance beyond the radial flange 35 and into contact with the radial flange 15 on the sleeve 13. The outer` end of the roll 36 is materially reduced as indicated at 36a.

A combined radial and thrust bearing` 37 is' confined upon the reduced portion of the roll shaft 36 and a suitable bearing cap 38 surrounds the combined radial and thrust bearing and is attached to the end of the bearing 32 whereby the roll 36 is rotatably anchored against longitudinal movement. The bearing sleeve 34 is however longitudinallyv adjustable through the instrumentality of the screw rod 30 and for this purpose a pair of nuts 39 are threaded upon the sleeve adjacent the rear end of the bearing block27. whereby the bearing sleeve 34 is constrained to move with the block 27. Itwill be noted that there is "a suitable space 40 between the outer end of thesleeve 34 and the end of the cap 38 to allow for the longitudinal adiustment of the sleeve 34. It will be noted that the roll- 36 is provided with a long keywav 41 for receiving the key 42 in the sleeve 34 to allow for relative adjustment. A spur gear 43 is secured upon the sleeve .34 adiacent the bearing 32 and this spur gear meshes with a pinion 44 which Iis secured unon a shaft 45 which is suitably journalled in the frame 1 and which is coupled to the motor shaft 46 of the aforementioned motor 2. It will be noted that the pinion 44 is vconsiderably longer than the width of the gear wheel 43 so that the longitudinal-adjustment of the gear 43 in connectionr with its' supporting sleeves will always be in mesh-with said pinion.

With reference to Figure 1, it will be noted that the axes of the rolls 16 and 36am normally in spaced relation and that the end of each roll contacts the opposite radial flange whereby a closed pass is formed through which a ring 47 may pass during the rota- .rotation of the sleeve. Consequently, there is b ound to be a certain amount of drag between the ring 47 and the said flanges. This draw is likelyto produce what is known as crosscutting or serrating the ring. To eliminate this crossecutting. as much as possible, the flanges 15 and 35 or at least one of them may be rotatably mounted upon its sleeve as shown in Figures 5 and 6.

ln referring to Figure 5, it will be noted that the sleeve 34a which is mounted in the bearing block 27a is provided with a terminal flange 35a rotatably mounted upon the sleeve 34a and that the ring 47 bears against the rotatable flange 35a. In order to prevent lore gitudinal movement of the rotatable flange 35a, the end of the sleeve 34a is provided with a groove 48 in which a rib 49 on the inner periphery of the flange 35a extends'. A thrust bearing 50 of any approved design is preferably mounted between the rotatable or floating ring 35a and the bearing block 27a and if desirable acircular bearing 51`having termin al ribs 52 which respectively fit in grooves in the floating ring 35a and the bearing block 27a may be used. Of course. the ribs 52 that enga ge the floating flange 35a should have a sufficiently loose fit to allow free rotation of said flange.

In Varying the size of the ring-pass, the roll 16 may be longitudinally shifted by operating the hand wheel 22. The roll 36 is however not longitudinally adjustable. The sleeve 34 that carries the roll 36 is however relatively adiustable to its roll by means of the slidable bearing 27 whereby it becomes possible to vary the width of the ring-pass.

In vorder to vary the radial thickness of a scription Each roll has an independent motor for operating the same, whereby different velocities of the rolls is possible to compensate for the differences between the inner and outer circumferences of the ring.

From the foregoing it willl be appreciated that a very simple structure has been provided in which the roll-pass may be readily varied to any width within its range with uit changing the rolls and in which the adjustments may be readily and speedily effected wilthout loss of'time or without much difficu ty.

Iam aware that many changes may be made and numerous details of construction may be varied through a wide range without departing from the principles of this invention and I, therefore, do not purposer limiting the patent granted hereon, otherwise than necessitated by the prior art.
